In the present instance, the track 15 is shaped after the fashion of thebottom of a saucer, while the rollers 'l-l taper toward the axis of theplatform and engage the track adjacent to the highest point thereof.

Rotatably mounted within the king post 10 is a vertical shaft 16 havingthe. lower end thereof equipped with a bevel pinion 1T meshing with asimilar pinion 18 fast upon the drive shaft 6 so that when the shaft 16is revolved motion will be imparted to the drive shaft. Secured to theupper surface of the base of the truck concentrically of the saucer-likebearing is a toothed annulus 19 and meshing with the annulus ll) is apinion 20 fast upon the lower end of a vere tical shaft 21 passedthrough. the platform adjacent to one side edge of the latter andmounted withina suitable bearin By means of this construction, it willbe seen that when motion is imparted to the shaft 21 the pinion meshingwith the annulus on the base of .the platform will revolve about suchannulus planet fashion with the effect to revolve the platform.

Journaled in horizontally alining h arings arranged transversely of theplatform is a main drive shaft 22 disposed above the upper end of theshaft 21. This main drive shaft is connected up with an appropriate formof driving motor 23 and keyed thereon is a bevel pinion 24 adapted tomesh with a similar pinion 25 splined upon the upper end of the shaft 21for sliding movement. Formed on the lower face of the bevel pinion antldepending therefrom is a ring 26 formed with a peripheral groove anddisposed wigpin the groove in the ring 26 is an annulusv .equipped atdiametrically oppopoints with outwardly projecting arms 2 'extendingbeyond the marginal edge of the pinion 25 and connected with the lowerextremities of vertical rods 29 depending from a cross bar 30 fastenedto the, lower end of a cord or cable 31, the other extremity of the cordorcablc being connected to and trained about a drum 32 rotatably mountedupon a shaft 33 supported in suitable stand ards spaced apart. Connectedwith one side wall of the drum 32 and extending radially therefrom is ahand lever 35 by means of which the drmn may be rotated about the shaft33. The rods 29 are slidably mounted within suitable guides 30 securedto the platform,"wbile connected with the arms 28 and dependingtherefrom are coiled contractile springs 37 having the lower endsthereof socured to a suitable support, such springs acting to slide thebevel pinion 25 normally downwardly along the shaft "21 out ofengagement with the pinion 24-.

Extending upwardly from the platform and disposed to one side of thepath of movement of the hand lever 33 is a segment 38 having the teeth39 thereof adapted to be engaged by the hand lever to maintain thelatter in the desired position. \Yhen it is desired to elevate thepinion 23 so as to engage the latter with the. pinion 24. in order thatthe shaft 21 will be rotated to revolve the platform about the kingpost. the hand lever 33 is swung downwardly thereby rotating the drum 3;and exerting a pull upon the cord 31 whereby the cross bar 250. and rods29. annulus 27 and bevel pinion are elevated and the teeth of the lattermeshed with the teeth of the pinion l-l. 'hen the pinions are broughtinto engagement. the hand lever 33 is engaged with the adjm-ent tooth 39on the segment 35 thereby maintaining the pinion 25 elevated against theaction of the springs 37. (hi the other hand. when the hand lever isdisengaged from the adjacent tooth of the segment and released. thesprings react and so lower the pinion 25 thereby disengaging the latterfrom the pinion on the main drive shaft.

Secured to the upper surface of the platform at opposite sides of theupper extremity of the shaft lo within the king post are forked brackets41). 41 alining transversely and pivoted within the bracket lt andmovable about a horizontal axis is a bearing 42, while slidably mountedwithin the bracket ll is a bearing l3 and jonrnaled in these aliningbearings is a shaft H disposed above the upper extremity of the shaft 16and keyed upon the shaft H is a bevel pinion 45 adapted to mesh with asimilar pinion 46 fast to the upper extremity of the shaft [6. ln thepresent instance. an inverted U- shaped yoke. 47 projects upwardly fromthe bracket 41 and secured to the interconneeting member of such yokeand depending therefrom is a coiled contractile spring 4R having thelower extremity thereof secured. to the bearing l l. This spring arts toslide the bearing 43 upwardly within the bracket 41 whereby the. shaftll will swin incident to the pivotal mounting of the bearing 42 withinthe bracket in. thereby disengaging the bevel pinion 45 from the pinion46. To swing the shaft downwardly against the action of the spring l9different means may be employed. Tn this case. a drum 49 is journaledupon a stub shaft projecting outwardly from the bracket i'l below thebearing 43 and fastened to the periphery of such drum is one end of acord so havilu the opposite end thereof secured to the bearing 43.(onneeted to the. drlun l9 and projecting upwardly therefrom is a. handlever Til whereby the drum may be rotated to exert apull upon the cord50 and so lower the for 19 Hum Jam-n an the 20 $1 mvmg; 14m

The upper extremities of the hars 88 and 89 constituting the standardsT, 87 are formed with alining openings through which are passed clampingbolts 100 wherehy the movahle har of each standard may he moved towardthe stationary liar to clamp the hearing hlock sliding therein and holdthe latter against movement as shown in Fig. 12. is one extremity of acord or eahle 101 and these, cords or ealiles are trained aroundsheaves-102 carried in blocks secured to the platform hclow the shaftsill and having the outer ends thereof fastened to a windlass 1oz;mounted upon the platform and operahlet'rom adiand wheel 104. By meansof this construction, it will be seen that when (onnected with eachhearing block hearing hlocks within such standards will he tree to movetherein so that the windlass may he operated to draw the blocksdownwardl within the standards to tighten thedriving belt 93, the.clamping holt-s being subsequently actuated to move the movable iars ofthe standards toward the stationary l ars to grip the hearing blocks.Thus, the driving helt of the digging mechanism may he at all times heldtaut to facilitate the operation of such mechanism.

in the present instance, the shifting mechanism for the clutch collar9o. shown in Fig. 4. comprises a lever 105 fulcrumed at one end as at101' and connected. centrally, with a ring 10? lying within a groove inthe peripher of the clutch collar 98. The outer end of the lever 105extends through and works within a horizontal Slot 108 formed in anupright 109 adjacent to the upper end thereof.

109 is equipped with vertically alinlng guides 110 and within the guides110 are. slidahly disposed, parallel guide bars 11]. carrying. at theirupper ends, a horizontal rack 112. while connected with the oppositeextremities of the rack bar are coiled contractilesprings 113 having theupper ends thereof secured to the upper edge of the upright. Dependingfrom the rack har H2 is a link 114 and the lowerend of the link ispivotally connected to a treadle 115 fulcrumcd at one end as at 116 tothe upright adjacent to the lower extremity of the latter. A coiledexpansion spring 117 surrounds the main drive shaft, 22 between theconfronting faces of the clutch collar 98 and sprocket. wheel 94and'acts to hold the teeth onthe clutch collar normally out ofengagement with the teeth on the sprocket wheel. \Vhen it' is desired toshift the clutch collar-so that the teeth thereof will engage with theteeth on the sprocket wheel, the treadle 115 is depressed, therebydrawing the rack bar 112 downwardly against the action of the springs113 was to release the lever 10?. The lever is now swung ah it itsfulcrum 106 and the ring connected erewith and disposedavithin thegroove in the clutch collar 98 activates 'the latter against the actionof the spring117 so that the teeth on the confronting faces ofitheclutch co lar and sprocket wheel 95 interlock thereby forming aconnection between the sprocket Below the slot 108 at the opposite endsthereof the outer face of the upright wheel and the main driveshaftwhereby the digging mechanism is actuated as previously described.Succeeding the clutching of the sprocket wheel to the shaft. the treadle'115 is released and the springs 113 react and draw the rack ha r112upwardly so that the teeth thereon engage the lever 105 and hold thelatter against return to normal position "tap star shaped rollers sothat the buckets thereonare carried tan-es under the action of thespring 117. To (lisengage the sprocket wheel from the shaft, the treadleis depressed controlling the-clutch reacts and so disengages the teethOJfrom the teeth 97.

ards- 58 adjacent to the upper ends thereof are supporting armslIS andjournaied in these arms is a horizontal shaft 119, while projectingrearwardly from the standards adjacent to the-lower extremities thereofare arms having the outer ends thereof equipped with horizontallyalining bear in which is journalecl a shaft 121. Fast uponthe shafts 119and 121 are four pointed star shaped rollers 122 an& over these rollersistrained an endless belt 123 constructed of any. suitable material.Fastened to the outer surfaces of the-rungs of the belt 123 are buckets124 spaced apart distances to the distances between the points at thethe latter will upon the buckets after the fashion of a sprocket Wheeland chain thereby rotating the belt and buckets thereon in the move mentof the rollers. In this embodiment of my invention,the oppositeextremities of the shaft 119 is provided with belt pulleys 125,

while the adjacent portions of the rlrire o shaft 83 are equipped withbelt pulleys v and over the-belt pulleys 125 and 126 are trained endlesscrossed belts 12'! whereby in the movement of the drive shaft on thedigging mechanism motion is imp: rte l to 5 the Shaft 119 to revolve thebelt 123 whereby around in the Sims direction as the buckets of theconveyer of the digging mechanism.

is desired to shil't the clutch collar against the action of the springs,lFi-l. The opposite eml ol" the cable or cord 155 is eonnectedto theperiphery of a drum 151$ journaled upon an axle. 157 carried byvertically disposed disks 15S spaced apart in parallelism and mountedupon a pedestal 159. Connected to the periphery ot the drum lot andprojecting radially therefrom is a. hand lever 1.00 by means otwhieh thedrum may be rotated in one. direction or the other to pull or releasethe cable. This hand lever is equipped with a. hitching dog lt'd adaptedto engage teeth 1(32 tormed upon the upper portion of the peripheiw' ofone of the disks 15R. \Vhen the lever is in the center ot the row ofteeth '16: the clutch collar is held spaced apart from between the.toothed faces of the gear wheel Ill and sprocket wheel l-lo so that inthe operation ot the main drive shaft the counterslml't 139 remainsidle. while when the lever isswung to one end of the row of teeth thecable is released and the springs 1 react andslide the clutch collaralong the shaft so that the particular set of teeth thereon interlockwith the adjacent set of teeth 15:; on the sprocket wheel 1%. ()n theother hand, when the lever is at the 0p posite end of the row of teeth162, the teeth on the opposite side of the clutch collar will interlockwith. the teeth of the gear wheel 1-H whereby the latter is con nectedwith the main drive shaft and the eountershattrotated in a directionreverse to the rotation thereof under the action of the sprocket wheels14-5 and lit; and the chain 117 as is readily apparent. 1

In operation. when it is desired to lower the digging mechanism from themain power shaft. the lever 16) is swung so as to exert a pull upon thecable or cord 155 and slide the clutch collar H8 so that the teeththereon will interlock with the teeth on the gear wheel 14+ therebyconnecting the countershat't with the main shaft so that the chain H2will be operated to revolve the shaft ()4 and lower the rack bars andmechanism carried thereby. ()n the contrary when it is desired toelevate the digging mechanism the latching dog on the hand lever 160 isdisengaged from the adjacent teeth and the hand lever swung to theopposite end of .the row of teeth thereby pern'iitting the springs 15-lto react and slide the clutch collar HR that the teeth thereon willinterlock with the teethot' the sprocket wheel 146 thereby connectingthe counters-bait with the main. shaft through the medium of thesprocket wheels 14-5 and 1-16 and the chain H7 whereby the countershaftwill be rotated in a direction reverse to themovement thereot' under theaction of the gear wheels 1423 and 144-. Thus. the shaft 64 will berevolved to elevate the digging mechanism.

In order to swing the standards about -their pivotal. connections withthe platform so that the digging mechanism and the conveyer receivingthe material from the digging mechanism may be swung or tilted to anydesired angle. relatively to the vertical and held in adjusted position.any suitable meehanisnrmay be employed.
